Caffeine Research Paper

Caffeine is a photoactive stimulant found in plant species. These plant species vary including tea, coffee and cocoa. The caffeine is absorbed fully into the stomach and small intestine after 30 to 45 minutes, which is the peak of the caffeine. The caffeine is in a person’s body for up to 4 hours. Caffeine has consequences if over dosed. Anxiety, heart palpitations, headaches, insomnia and nervousness are all physical and mental conditions that can be present if you have caffeinism. This research gives me an insight into caffeine I would have never known if I did not chose this topic to study.

Introduction: (bring a monster, sip it) alright. How many of you here drink coffee, energy drinks, or soda daily? Well we aren’t alone; according to Villanova Health Service about 90 percent of Americans consume caffeine in one way or another every single day.

Caffeine is an alkaloid that is found naturally in things such as nuts, leaves, and seeds. Caffeine is also known as 1,3,7-Trimethylxanthine, Thein, Methylbromine, Guaranine, Cafeina, Coffeinum N, Coffeinum Purrum, Dexitax, and Durvitan. The molecular weight of caffeine is 194.194 g/mol. The chemical formula for caffeine is C8H10N4O2. Caffeine also acts as an adenosine receptor protagonist. (PubChem.gov, 2004) Friedrich Ferdinand Runge was the first person to isolate caffeine. (Helmenstine, 2017) Caffeine is typically found in these plants: coffee plants, guarana, yerba mate, cacao

Waking up to a hot cup of coffee, relishing the cool tingling sensation of a cola with your lunch, or relaxing in the afternoon over a cup of tea, all have similar ingredient caffeine. Caffeine has been consumed ever since the 2700 BC, with its conjunction in tea, for the Chinese Emperor Shen Nung. In 575 AD, the first use of coffee beans where in Africa where it was used as currency and food. Even more today, caffeine consumption has become an integral part of millions of people's daily lives. According to David Weaver, "Caffeine and theophylline are among the most widely consumed neuroactive substances. These drugs are consumed most frequently in beverages, but also are present in certain over-the-counter diet aids, 'alertness

Caffeine is one of the most well-known orally consumed drug around the world. In the 1820s, a German chemist named Friedrich Ferdinand Runge first discovered caffeine by extracting it from coffee [6]. Coffee and tea are leading sources of caffeine in the adult diet whereas caffeinated soft drinks are leading sources of caffeine in the diet of children in North America [7]. The per capita consumption level of caffeine for consumers of all ages is approximately 120mg/day [4]. The purpose of this investigation is to conclude whether the regular consumption of caffeine is beneficial to human health.

What is Caffeine? Caffeine is a drug that is naturally produced in the leaves and seeds of the plants. Caffeine is defined as a drug because it contains a stimulant that affects the body's nervous system. Ever wonder what has caffeine in it? Well, it's in most of the daily refreshments that people consume. Such as, tea, coffee, and many soft drinks. Coffee is a little acidic and it can have a stimulating effect on humans because of its caffeine content. Teens usually get their caffeine from soft drinks and energy drinks. On the other hand, adults consume their caffeine from mostly coffee, and sometimes energy drinks when needed.

Caffeine in its purest form is a white color with a prismatic crystal form (1) and has a density of 1.23 g/cm³ (2). It is found in the leaves and beans of the coffee plant, in tea, yerba mate, and guarana berries, and in small quantities in cocoa, the kola nut and the Yaupon Holly. Overall, caffeine is found in the beans, leaves, and fruit of over 60 plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding upon them. Caffeine is a central nervous system (CNS) stimulant, having the effect of temporarily warding off drowsiness and restoring alertness. Caffeine is slighty soluble (3). And has a boiling point of 178°C (4) and a melting point of 238°C (5). Its molecular formula is C8H10 N4O2 and has an average mass of 194.190598 Da. Da stands for the Daltons (6).

Caffeine is the most widespread drug throughout the world being consumed daily by millions if not billions of people. In

Caffeine, or 1,3,7-trimethylxanthine, is a psychostimulant which, just like other classical psychostimulants, such as cocaine and amphetamines, increases motor activity, induces arousal, and creates reinforcing effects (Griffith & Woodson, 1998). It has multiple side effects which are produced by many biological mechanisms, the most important one being the inhibition of adenosine receptors (Green & Stiles, 1986).

What is caffeine? Caffeine is a compound present in over sixty plants, including coffee beans, tea leaves, cacao pods and kola nuts. Around, 90% of people use caffeine in their food or drinks. Most American’s drink it in the form of coffee. Some may drink it in the form of carbonated soft drinks, tea, or energy drinks. Most caffeine consumption is done by drinking coffee which is made with ground up coffee beans. How much coffee do we drink? According, to the Huffington Post. “Americans consume 400 million cups of coffee per day, equivalent to 146 billion cups of coffee per year, making the United States the leading consumer of coffee in the world.” That is only coffee. What about other products? Well according

From the journal of Core Concepts in Pharmacology, Holland and Adams (2007) have stated that Caffeine is a natural substance found in the seeds, leaves, or fruits of more than 63 plant species. Significant amounts of caffeine are consumed in coffee, chocolate, soft drinks and tea. Sometimes caffeine is added to over the counter pain relievers to help relieve migraines and other conditions. Caffeine travels to almost all parts of the body after ingestion, and several hours are needed for the body to metabolize and eliminate the drug. Caffeine is considered a central nervous system stimulant because it produces increased mental alertness, restlessness, nervousness, irritability and insomnia. The physical effects of caffeine include bronchodilation, increased blood pressure, increased production of stomach acid , and changes in blood glucose levels. Repeated use of caffeine may result in physical dependence and tolerance. The serving size of a brewed and instant coffee is 8 ounces and containing 95 to 135mg of caffeine while the serving size for decaffeinated coffee is 8 ounces containing 5mg.

Caffeine is an alkaloid, which is commonly found in coffee, tea, and pop (Shahab). It has many health benefits, as well as its disadvantages. Drinking caffeine protects the liver. It has been

Caffeine has a long history of consumption. It was first found in the form of coffee which was discovered around 1,000 years ago in the region now known as Ethiopia. The first coffee shipment to Europe was around 1615. Rapid growth of popular coffee houses spread from the mid-17th century as they became favourite meeting places. Till to date, it is the world’s most widely consumed psychoactive drug. It is legal and unregulated in nearly all parts of the world, unlike many other psychoactive substances. Caffeine, a bitter substance found in coffee, tea, soft drinks, chocolate, kola nuts, and certain medicines (MedilinePlus, 2015), is a central nervous system stimulant of the methylxanthine class. Caffeine intake is so common

My research question is "What are the effect of caffeine on blood pressure and heart rate on adults in different times of the day, different aged people and gender?" This research question is significant and worthy of study because many of us take drinks filled with caffeine in them and would want to know what happens to our body when caffeine is ingested. I will measure the heart rate and blood pressure after drinking the beverage containing caffeine. The research question is significant to me personally because I drink a lot of Coca-Cola, tea and coffee and so I am worried about what caffeine does to my body. I will be measuring the heart rate and blood pressure before the ingestion of caffeine and 60 minutes after the ingestion of caffeine. I will do this so I can compare the ‘before and after' effect.
